I wear a size 12. I came across an eBay listing for a vintage C&A skirt. Unsure of year but it was made in UK so likely to be 80s or earlier.
It's a size 12 but on the label says will fit waist 24". It's been a long time since someone wearing a size 12 would have had a 24" waist my thighs aren't far off that.
Vanity sizing really is hiding how fat we all are, isn't it?
